DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0030] like Figure 1 , Figure 2As shown, this embodiment proposes that the present application provides a magnetic lamp holder for installation on a vehicle frame, such as a bicycle handlebar frame. It is used in conjunction with a vehicle lamp body, the vehicle lamp body is connected to the lamp holder, and used as a vehicle lamp; the vehicle lamp body is disassembled and used as a handheld lighting lamp. The magnetic lamp holder of this embodiment mainly includes: a seat body 100, an elastic clamping member 200, and a magnetic member 300. For the convenience of structural description, the seat body 100 adopts a square structure, and its thickness direction is the up-down direction. The outer contour of the seat body 100 is a rectangle, with the direction of the long side as the length direction (front-to-back direction), and the direction of the short side as the width direction (left-to-right direction). The length direction of the seat body 100 has a first end (front end) and a second end (rear end) opposite to each other. A magnetic mounting hole 110 is provided on the front end surface of the seat body 100, and the magnetic mounting hole 110 extends a predetermined length in the front-to-back direction. The bottom of the magnetic mounting hole 110 away from the bottom surface of the front end surface forms a hole bottom, and the hole bottom serves as a bearing surface 111. The elastic retaining member 200 is arranged in the magnetic component mounting hole 110. The elastic retaining member 200 is elastic and can expand or reduce the channel size of the magnetic component mounting hole 110 through its elastic action. The elastic retaining member 200 has a magnetic component stop surface 221 on the side facing the bearing surface 111, that is, the rear end surface of the elastic retaining member 200 is vertically arranged as the magnetic component stop surface 221, and the magnetic component stop surface 221 is spaced a distance from the bearing surface 111, and the space between the intervals forms a magnetic retaining member 120. The magnetic attraction member 300 can be made of a material with attraction such as a magnet or a magnet, or it can be a metal member that can be magnetically attracted, and it only needs to be attracted to the magnetic member on the headlight body. The magnetic member 300 is finally installed in the magnetic member clamping position 120 and is limited by the magnetic member stop surface 221 and abuts against the bearing surface 111; the rear end surface of the magnetic member 300 located in the magnetic member clamping position 120 abuts against the bearing surface 111 at the bottom of the magnetic member installation hole 110 and is limited at the rear end, and the front end surface of the magnetic member 300 is also limited due to the obstruction of the magnetic member stop surface 221, and the outer periphery of the magnetic member matches the inner side wall of the magnetic member installation hole 110, so that the magnetic member 300 is stably installed in the seat 100. During the installation process of the magnetic member 300, the elastic clamping member 200 is squeezed by the magnetic member 300 and deforms and gives way, so that the magnetic member 300 enters the magnetic member clamping position 120.

[0031] A magnetic lamp holder proposed in this embodiment has a magnetic mounting hole 110 formed on the holder body 100, and an elastic retaining member 200 is disposed in the magnetic mounting hole 110. The elastic retaining member 200 is elastic and deforms, thereby expanding or reducing the channel size of the magnetic mounting hole 110. During the process of installing the magnetic component 300, when the magnetic component 300 passes through the magnetic component installation hole 110, the elastic clamping member 200 is squeezed by the magnetic component 300 and deforms and gives way, so that the channel of the magnetic component installation hole 110 gradually becomes larger, so that the magnetic component 300 enters the magnetic component clamping position 120 from the enlarged channel, and at this time, the elastic clamping member 200 is separated from the squeezing of the magnetic component 300 and returns to its original state, so that the enlarged channel of the magnetic component installation hole 110 becomes smaller, so that the magnetic component stop surface 221 on the elastic clamping member 200 blocks and limits the withdrawal direction of the magnetic component 300, so that the magnetic component 300 is limited against the bearing surface 111 and is fixed in the magnetic component clamping position 120. In this process, the magnetic component 300 can be installed in place by only pushing it, and the magnetic component 300 can be fixed without bonding, avoiding the problem of the magnetic component 300 falling off due to aging and failure after long-term use by using glue.

[0032] like Figure 1 , Figure 2 As shown, further, the elastic retaining member 200 in this embodiment specifically includes: an elastic arm 210 and an inner boss 220. The front end of the elastic arm 210 is connected to the base 100, and the rear end of the elastic arm 210 is connected to the inner boss 220, so that the inner boss 220 is extended toward the central axis of the magnetic component mounting hole 110, so that the inner boss 220 protrudes toward the central axis direction of the magnetic component mounting hole 110, so that the inner boss 220 is located in the channel of the magnetic component mounting hole 110. The inner boss 220 is connected by the elastic arm 210 to realize a cantilever beam structure, so that the inner boss 220 located at the end of the elastic arm 210 can move. Therefore, the inner boss 220 is movably arranged along the central axis away from or toward the magnetic component mounting hole 110 through the deformation of the elastic arm 210, so that the channel size of the magnetic component mounting hole 110 can be expanded or reduced. The magnetic component stop surface 221 is located at one end of the inner boss 220 facing the bearing surface 111; the magnetic component stop surface 221 located at the rear end of the inner boss 220 is a vertical surface. After the elastic arm 210 returns to its original state, the magnetic component stop surface 221 is located at the front side of the magnetic suction component 300, and can prevent the magnetic suction component 300 from withdrawing forward from the magnetic component position 120 by abutting against the front end surface of the magnetic suction component 300.

[0033] like Figure 1 , Figure 2As shown, further, the inner boss 220 in this embodiment is provided with an inclined pressure surface 222 on one side of the first end of the seat body 100, and the inclined pressure surface 222 gradually approaches the central axis of the magnetic component mounting hole 110 along the direction toward the bearing surface 111. In the specific structure, the inner boss 220 can adopt a similar triangular structure, and the front surface of the inner boss 220 is an inclined pressure surface 222, and the inclined pressure surface 222 gradually protrudes toward the central axis of the magnetic component mounting hole 110 along the front-to-back direction. When the magnetic attraction component 300 enters the magnetic component mounting hole 110, it is gradually pushed to the inclined pressure surface 222, and the inclined pressure surface 222 is squeezed and opens in the direction away from the central axis of the magnetic component mounting hole 110, thereby slowly opening the channel of the magnetic component mounting hole 110, and the magnetic attraction component 300 can be smoothly and stably pushed into the magnetic component clamping position 120.

[0034] like Figure 1 , Figure 2 As shown, further, in this embodiment, a void hole 130 is provided on the outer wall of the seat body 100, and the void hole 130 is connected to the magnetic component mounting hole 110; the elastic clamping member 200 is located in the void hole 130 and connected to the inner wall of the void hole 130. The use of the void hole 130 can increase the elastic performance of the elastic clamping member 200. In the specific structure, the void hole 130 can be provided on the outer wall of the seat body 100 in the up, down, left and right directions, the front end of the elastic arm 210 is fixedly connected to the inner wall of the void hole 130 and extends toward the rear end in the void hole 130, and the inner boss 220 at the rear end of the elastic arm 210 is spaced a predetermined distance from the inner wall of the void hole 130, thereby forming the above-mentioned magnetic component clamping member 120. Since the outer side of the elastic arm 210 forms a cantilever due to the void of the void hole 130, the elastic arm 210 is more likely to produce elastic deformation, and when the inner boss 220 is squeezed, a larger deformation can be produced.

[0035] like Figure 1 , Figure 2 As shown, further, in this embodiment, two elastic retaining members 200 are provided, and the two elastic retaining members 200 are arranged in a mirror-symmetrical manner in the magnetic component installation hole 110. In the specific structure, the two elastic retaining members 200 are respectively arranged in the avoidance holes 130 opened in the upper and lower directions of the seat body 100, and are arranged symmetrically in the upper and lower directions, so that during the advancement and installation process of the magnetic suction member 300, the upper and lower directions are subjected to uniform force, and the inclined pressure-bearing surface 222 in the upper and lower directions forms a symmetrical conical channel, which has a guiding and centering function, so that the magnetic suction member 300 can be stably advanced into the magnetic component retaining position 120 along the central axis.

[0036] like Figure 1 , Figure 2As shown, further, a magnetic through hole 140 is provided on the second end of the seat 100 in this embodiment, and the magnetic through hole 140 is connected to the magnetic mounting hole 110, and the inner diameter of the magnetic through hole 140 is smaller than the magnetic mounting hole 110. The magnetic suction member 300 includes a first column 310 and a second column 320, and the diameter of the second column 320 is smaller than the first column 310. The first column 310 is embedded in the magnetic clamp 120, and the second column 320 is embedded in the magnetic through hole 140. By setting the magnetic suction member 300 into an axis structure of different sizes, the second column 320 is matched and embedded with the magnetic through hole 140, so that the magnetic suction member 300 can expose the outer end of the second seat 100, and when it is magnetically attracted to the external headlight body, it can provide a greater suction force and enhance the magnetic suction force. Moreover, a stepped hole is formed between the magnetic through hole 140 and the magnetic installation hole 110, and the outer wall of the magnetic through hole 140 can match the second column 320 to achieve circumferential limitation. The distance of the magnetic clamp 120 along the front-to-back direction is the same as or slightly greater than the front length of the first body. The magnetic clamp 120 limits the front-to-back direction of the first column 310, thereby making the fixation of the magnetic attraction member 300 more stable.

[0037] like Figure 1 , Figure 2 As shown, further, a core-pulling groove 141 is provided on the inner wall of the magnetic through hole 140 in this embodiment at a position corresponding to the elastic retaining member 200. The elastic retaining member 200 is integrally formed with the seat body 100, and the core-pulling groove 141 is used for core-pulling to form the inner boss 220 during the integral forming. The core-pulling groove 141 mainly provides a core-pulling position for the core in the mold, so that the inner boss 220 protruding toward the inner side of the magnetic mounting hole can be formed on the elastic arm 210, which is convenient for molding processing.

[0038] like Figure 2 , Figure 3 As shown, further, the second end of the seat body 100 in this embodiment is provided with a plug-in cavity 152, and the plug-in cavity 152 is used to plug the lamp body so that the lamp body is magnetically connected to the magnetic member 300. The rear end of the seat body 100 is connected to the lamp body through the plug-in cavity 152. When the front end of the lamp body is inserted into the plug-in cavity 152, the circumference of the lamp body is limited, the front end of the lamp body is magnetically connected to the magnetic member 300, and the circumference of the lamp body is surrounded by the plug-in cavity 152, thereby ensuring the stability of the connection between the lamp body and the lamp holder.

[0039] like Figure 2 , Figure 3As shown, further, the second end of the seat body 100 in this embodiment is provided with a bracket 150 and a pressing frame 151, and the bracket 150 and the pressing frame 151 are arranged at intervals to form a plug-in cavity 152. In the specific structure, the bracket 150 is arranged at the lower part of the rear end of the seat body 100, and the pressing frame 151 is arranged at the upper part of the rear end of the seat body 100. A semi-enclosed cavity is opened on the bracket 150, and the lower part of the vehicle lamp body can be limited by the semi-enclosed cavity. The pressing frame 151 is arranged at intervals from the bracket 150, so that the pressing frame 151 is located at the top to form a cantilever plate structure, which has a certain elastic yielding performance, and facilitates the insertion of the vehicle lamp body into the plug-in cavity 152.

[0040] like Figure 2 , Figure 3 As shown, further, hooks 160 are respectively provided on both sides of the seat body 100 in this embodiment, and elastic bands 161 are detachably connected to the hooks 160. The elastic bands 161 are used for bundling, which is convenient for disassembly. The elastic bands 161 are elastic loops. When in use, the lamp holder is placed on the vehicle frame, the elastic loop is stretched, one end of the elastic loop is hung on the hook 160 on one side, and the other end is hung on the hook 160 on the other side after passing from the side of the vehicle frame away from the lamp holder. Under the elastic force of the elastic bands 161, the lamp holder is installed on the vehicle frame. With this structure, the lamp holder can be quickly disassembled from the vehicle, which is convenient for use.

[0041] In summary, a magnetic lamp holder in the present application has a magnetic mounting hole formed on the holder body, and an elastic retaining piece is arranged in the magnetic mounting hole. The elastic retaining piece is elastic and deforms, so that the channel size of the magnetic mounting hole can be expanded or reduced. The magnetic part can be installed in place by just pushing it, and the magnetic part can be fixed without bonding, thus avoiding the problem of the magnetic part falling off due to aging and failure caused by bonding with glue after a long period of use. The lamp holder is fixed to the vehicle frame, and the lamp body is magnetically connected to the lamp holder to be used as a vehicle lamp; the lamp body is disassembled and used as a handheld lighting lamp to improve the practicality of the vehicle lamp.
